Leaf Wetness Sensors

Emulate leaf surface

237-L Wetness Sensing Grid

Wetness Sensing Grid
  • Following calibration by user, detects periods of leaf wetness caused by rainfall, dew, or spray
  • Measures electrical resistance between interlacing gold-plated fingers on circuit board
  • Size and smoothness of sensor emulates surface area of leaf

About Leaf Wetness Sensors

Leaf wetness sensors are classified as:
- Surface contact types that measure the electrical resistance of a water film on the leaf surface,
- Mechanical types that detect a change in sensor length or weight, or
- Electrical resistance types that are applied to mock leaves and are designed to emulate periods of leaf wetness after rainfall, dew, or spray.
